CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority from U.S. ProvisionalApplication No. 61/596,506, filed Feb. 8, 2012.

FIELD OF THE INVENTION

The present invention relates to personal care compositions comprising aconditioning particle complex. More particularly, the present inventionrelates a method for forming a large particle complex comprisinghydrolyzed corn starch, starch/cellulose polymer, hydrogenatedphospholipid, and gum arabic. The particle complex is capable ofdelivering volumizing, fixative, and conditioning benefits as acomponent of a sprayable leave-on personal care composition.

BACKGROUND OF THE INVENTION

People with fine or thin hair often use “volumizing” shampoos in orderto add volume and body to their hair. Conventional volumizing shampoos,however, possess certain drawbacks such as, for example, a failure toprovide real volume benefits as the effective ingredients are too heavyon the hair, thereby weighing it down. Another drawback associated withvolumizing shampoos is their inability to provide appreciable stylingattributes and wet-conditioning onto hair treated therewith.

Most products achieve their volumizing benefits by combining varioussynthetic ingredients based on combinations of polyvinyl pyrrolidone(PVP), vinyl acetate (VA), and acrylates to form a film on the hair toadd volume, hold and style. But consumers increasingly desire volumizingcompositions which provide volume with natural ingredients.

Thus, there is an ongoing need for naturally-based hair carecompositions which confer volume to the hair, improve the stylingattributes and enhance the wet combability, and which do not leave thehair stiff or excessively sticky.

SUMMARY OF THE INVENTION

A method for forming a large particle complex comprising the steps ofcombining a hydrolyzed corn starch polymer, a starch/cellulose polymer,a hydrogenated phospholipid, and gum arabic in a cosmetically acceptablecarrier to form a premix composition; heating said premix to about 85°C. for about 15 minutes; and cooling the composition to roomtemperature.

The particle complex is useful as a component of a sprayable compositionwhich provides volumizing, hair fixing, and conditioning as a leave-ontreatment for human hair.

DETAILED DESCRIPTION OF THE INVENTION

While the specification concludes with claims that particularly pointout and distinctly claim the invention, it is believed the presentinvention will be better understood from the following description.

All percentages, parts and ratios are based upon the total weight of thecompositions of the present invention, unless otherwise specified. Allsuch weights as they pertain to listed ingredients are based on theactive level, and, therefore, do not include solvents or by-productsthat may be included in commercially available materials, unlessotherwise specified. The term “weight percent” may be denoted as “wt. %”herein.

All molecular weights as used herein are weight average molecularweights expressed as grams/mole, unless otherwise specified.

Herein, “comprising” means that other steps and other ingredients whichdo not affect the end result can be added. This term encompasses theterms “consisting of” and “consisting essentially of”. The compositionsand methods/processes of the present invention can comprise, consist of,and consist essentially of the essential elements and limitations of theinvention described herein, as well as any of the additional or optionalingredients, components, steps, or limitations described herein.

The term “polymer” as used herein shall include materials whether madeby polymerization of one type of monomer or made by two (i.e.,copolymers) or more types of monomers.

The term “solid particle” as used herein means a particle that is not aliquid or a gas.

The term “water-soluble” as used herein, means that the polymer issoluble in water in the present composition. In general, the polymershould be soluble at 25° C. at a concentration of at least 0.1% byweight of the water solvent, preferably at least 1%, more preferably atleast 5%, most preferably at least 15%.

The term “water-insoluble” as used herein, means that a compound is notsoluble in water in the present composition. Thus, the compound is notmiscible with water.

Hydrolyzed Starch Polymer

The personal care compositions of the present invention comprisewater-soluble hydrolyzed starch polymers. As used herein, the term“hydrolyzed” refers to a starch which is degraded, for example, byenzymes (incomplete hydrolysis) or acid (complete hydrolysis).

The personal care compositions comprise hydrolyzed starch polymers at arange of about 0.01% to about 10%, and more preferably from about 1% toabout 7%, and most preferably from about 2% to about 4% by weight of thecomposition.

The hydrolyzed starch polymers generally have a molecular weight fromabout 250,000 to about 15,000,000. As used herein, the term “molecularweight” refers to the weight average molecular weight. The weightaverage molecular weight may be measured by gel permeationchromatography (“GPC”) using a Waters 600E HPLC pump and Waters 717auto-sampler equipped with a Polymer Laboratories PL Gel MIXED-A GPCcolumn (Part Number 1110-6200, 600×7.5 mm, 20 um) at a columntemperature of 55° C. and at a flow rate of 1.0 ml/min (mobile phaseconsisting of Dimethylsulfoxide with 0.1% Lithium Bromide), and using aWyatt DAWN EOS MALLS (multi-angle laser light scattering detector) andWyatt Optilab DSP (interferometric refractometer) detectors arranged inseries (using a dn/dc of 0.066), all at detector temperatures of 50° C.,with a method created by using a Polymer Laboratories narrow dispersedPolysaccharide standard (Mw=47,300), with an injection volume of 200 μl.

The hydrolyzed starch polymers may comprise maltodextrin. Thus, in oneembodiment of the present invention, the hydrolyzed starch polymers maybe further characterized by a Dextrose Equivalance (“DE”) value of lessthan about 35, and more preferably from about 1 to about 20. The DEvalue is a measure of the reducing equivalence of the hydrolyzed starchreferenced to dextrose and expressed as a percent (on dry basis). Starchcompletely hydrolyzed to dextrose has a DE value of 100, andunhydrolyzed starch has a DE value of 0. A suitable assay for DE valueincludes one described in “Dextrose Equivalent”, Standard AnalyticalMethods of the Member Companies of the Corn Industries ResearchFoundation, 1st ed., Method E-26. Additionally, the hydrolyzed starchpolymers of the present invention may comprise a dextrin. Dextrin istypically a pyrolysis product of starch with a wide range of molecularweights.

The source of starch before hydrolysis can be chosen from a variety ofsources such as tubers, legumes, cereal, and grains. Non-limitingexamples of this source starch may include corn starch, wheat starch,rice starch, waxy corn starch, oat starch, cassava starch, waxy barley,waxy rice starch, glutenous rice starch, sweet rice starch, amioca,potato starch, tapioca starch, oat starch, sago starch, or mixturesthereof.

The personal care compositions include at least hydrogenatedphospholipid. Suitable hydrogenated phospholipids include those whichare formed synthetically or, more preferably, by hydrogenation ofnaturally occurring phospholipids, e.g. phospholipids previouslyisolated from eggs or soy. Preferred hydrogenated phospholipids includehydrogenated lecithin such as Lecinol S-10, available from Barnet.

The personal care compositions of the present invention comprise thehydrogenated phospholipid at a level of from about 0.1% to about 2%,more preferably from about 0.2% to about 1.5%, and most preferably fromabout 0.3% to about 1.0% by weight of the composition.

Hair Conditioning Complex and Method

Method of Making

The compositions of the present invention include the aforementionedhydrolyzed corn starch, starch/cellulose polymer, hydrogenatedphospholipid, and gum arabic which form a complex according to thecompositions herein.

The complex may be formed by combining the hydrolyzed corn starch,starch/cellulose polymer, hydrogenated phospholipid, and gum arabic inan aqueous carrier to form a premix, prior to addition of otheringredients. The mixture is heated to about 85 degrees for about 15minutes, during which time, additional water or oil soluble actives mayoptionally be added. Then the mixture is cooled to room temperature.Additional ingredients, including electrolytes, polymers, fragrance, andparticles, may be added to the product at room temperature. The mixtureis mixed under low shear throughout the entire process, but it is nothomogenized.

In one embodiment, the compositions may be substantially free ofvolatile alcohols such as ethyl alcohol or isopropyl alcohol. The term,“substantially free” as used herein means that no more than traceamounts of a material may be present in the composition, and preferablynone of a material is present in the composition.

Particle Complex

It is believed that mixing in the absence of homogenization forms acomplex of relatively large particle size. The complex is comprised ofthe hydrogenated phospholipid, hydrolyzed starch polymer, gum arabic,and starch/cellulose polymer.

The complex, in solution, has an average particle size of from about 100to 200 micrometers, more preferably from about 110 micrometers to about190 micrometers, and most preferably from about 120 micrometers to about180 micrometers.

It has been found that the complex forms most effectively when combinedat particular ratios of one ingredient to another. For example, thehydrolyzed starch polymer is generally incorporated at a ratio of about3:1 relative to the starch/cellulose polymer to form a first blend. Thehydrogenated phospholipid is generally incorporated at a ratio of about8:1 relative to the gum arabic to form a second blend. And the ratio ofthe first blend to the second blend is generally about 5:1 in thecomposition.

Importantly, the composition is not homogenized. Homogenizationtypically results in particles having a particle size of less than about100 micrometers. It has been surprisingly discovered that formation ofthe complex herein, having a larger particle size, versus homogenizedsystems, provides enhanced sensory benefits to hair. Further, smallerparticle sizes are generally thought to enhance sprayability of liquidcompositions. But it has been found that the complex herein is highlysprayable even at its relatively high particle size. Particle size ismeasured using a Hydro S sample dispersion unit from Malvern.

The composition including the complex herein generally has a viscosityof from about 800 to about 1500 cps, preferably from about 900 to about1400 cps. Viscosity is measured using a Brookfield LV viscometeraccording to the following specifications: LVT, spindle 2, 12 rpm, at25° C.
